Patented May 15, 1945 NiTED STATES OFFHCE This invention relates to awire twisting tool, and has for the primary object the provision of atool of the above stated character which is especially adapted fortwisting together strands of wire which have the ends thereof mounted orsecured to a support and to permit the operation to be carried out witha maximum amount of safety to the operator and with a minimum amount ofmanual effort.

With these and other objects in view as will become more apparent as thedescription proceeds, the invention consists in certain novel featuresof construction, combination and arrangement of parts as will behereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had tothe following description and accompanying drawings, in which Figure 1is an end elevation illustrating a wire twisting tool constructed inaccordance with my invention.

Figure 2 is a vertical sectional view illustrating the tool with thestrands of wire applied thereto.

Figure 3 is a fragmentary transverse sectional view showing the holderand the ratchet mechanism for the wire twisting element.

Figure 4 is a sectional view taken on the line l i of Figure 3.

Figure 5 is a top plan view illustrating the wire twisting element.

Figure 6 is a perspective view illustrating a dog forming a part of theratchet mechanism.

Figure 7 is a perspective view of a pin forming a part of the wiretwisting mechanism.

Referring in detail to the drawings, the numeral 5 indicates the holderof the tool which consists of a substantially tubular shaped body 5having a slot or entrance 1 formed in a wall thereof and eXtending thefull length of the body. A tubular sleeve 8 is formed integrally withthe body 6 opposite the entrance 1 and the bore thereof is partly screwthreaded to have a handie 9 threaded therein. The bore enters the bodyof the holder and provides a mounting for a dog Hi spring influenced bya coil spring ll interposed between the handle and the dog. Oppositewalls of the sleeve are provided with slots l2 in which operates a pinI3 carried by the dog and provides means whereby the dog may be movedinto a retracted position against the action of the spring H.

The bore of the body has an internal shoulder M decreasing the diameterof a portion of the bore and in which is formed an annular groove orseat IE to receive spring influenced detents I6 of a wire twistingelement ll capable of rotation within the bore of the body.

The wire twisting mechanism consists of a tubular body 18 provided withan external shoulder l9 to abut the shoulder M when the detents engagethe seat. The body I8 is composed of half sections connected by a pivotpin 20 for hinging movement, the free ends of the sections beingnotched, as shown at 2!. The body It has formed on its periphery ratchettype teeth 22 coacting with the dog I ll in locking the body of thetwisting mechanism to the body of the holder 5 when the handle 9 isswung in one direction and to permit the body of the holder to turn freeof the body of the twisting mechanism when the handle is swung in areverse direction.

A pin 23 is apertured to receive the pin 20 and traverses the bore ofthe body I8 with its free end fitting in the notches 2|.

In use the pin 23 is adapted to extend between supported wires 2 asshown in Figure 2, and by swinging the handle first in one direction andthen in the other direction relative to the wires, said wires will becaused to twist about each other with a maximum amount of safety to theoperator and with a minimum amount of elfort. Whenever it is desired torelease the dog it] from the ratchet teeth, the operator places pressureon the pin 13 in the direction of the handle.

To apply and remove the tool to the supported wires 24, the body N3 ofthe twisting mechanism is moved endwise from the body of the holder. Thesections of the body 18 then may be swun apart so that the body 18 maybe either placed over or removed from the wire and when placed thereonthe pin 23 extends between the wires. After the body It has been appliedto the wires, the body 6 of the holder may be placed over the wires bypermitting the wires to enter the body by Way of the entrance I. Thebody ii is then moved onto the body 18 of the twisting mechamism untilthe detents engage in the seat I5. The

holder, a twisting element journaled in the bore of the body andremovable therefrom said twisting element being constructed oflongitudinally split sections hingedly connected to each other at onelongitudinal edge of the sections, and a ratchet mechanism connectingthe twisting element to the holder.

2. In a wire twisting tool, a holder having a bore and an entrance topermit supported wires to enter and leave the bore, a tubular sleeve onthe holder opposite the entrance, at handle secured in the sleeve, aspring influenced dog operable in the sleeve and extending into thebore, a twisting element journaled in the bore of the body and removabletherefrom said twisting element being constructed of longitudinallysplit sections hingedly connected to each other at one longitudinal edgeof the sections, and ratchet teeth formed on the twisting element andcoacting with the dog.

3. In a wire twisting tool, a holder having a bore and an entrance topermit supported wires to enter and leave the bore, a sleeve formed onthe holder opposite the entrance, a handle secured in the sleeve, aspring influenced dog mounted in the sleeve and entering the bore, a,longitudinally split sectional body journaled in the bore and removabletherefrom, a pivot connecting one longitudinal edge of the sections toeach other, ratchet teeth formed on the body and coacting with the dog,and a pin traversing the body.

4. In a wire twisting tool, a holder having a bore and an entrance topermit supported wires to enter and leave the bore, a sleeve formed onthe holder opposite the entrance, a handle secured in the sleeve, aspring influenced dog mounted in the sleeve and entering the bore, alongitudinally split sectional body journaled in the bore and removabletherefrom, a pivot connecting one longitudinal edge of the sections toeach other, ratchet teeth formed on the body and coacting with the dog,said sections of the body having the free ends thereof notched, a

twisting pin carried by the pivot and fitting in the notched ends of thebody.
